Abstract: A torsion device is adjustable for providing a predetermined torsion curve, and includes two external connecting members and N numbers of torsion modules, in which 2≤N. Each torsion module includes a plurality of stacked torsion washers, an interlocking unit, and two shafts passing through the torsion washers and the interlocking unit. The two shafts of each torsion module are rotatable relative to each other in an angle range so as to generate a torsion curve, the N numbers of the torsion modules generate M kinds of torsion curves different from each other, and 2≤M≤N. The predetermined torsion curve is formed by adding at least two of the M kinds of the torsion curves, and at least two of the N numbers of the torsion modules corresponding to the predetermined torsion curve are fixed to the two external connecting members.
